If you are using all Microsoft Office applications, chances are object.Activate() method will work. This is part of Microsoft VBA and C# application calls that are also available to 3rd party languages. Code below was tested on my Windows 10 environment, python 3.7 with pywin32, and MS-Office 2013. 

####### Activate one excel file ##############
import win32com.client as win32
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb1 = excel.Workbooks.Open(r'C:\python\so\sheet1.xlsx')
wb2 = excel.Workbooks.Open(r'C:\python\so\sheet2.xlsx')
wb3 = excel.Workbooks.Open(r'C:\python\so\sheet3.xlsx')    
excel.Visible = True

# This will open 3 workbooks with wb1 on top.

excel.Application.ActiveWorkbook.Name
# Prints name of currently active workbook, i.e., the one on top.

wb3.Activate()  # puts workbook3 on top
wb2.Activate()  # puts workbook2 on top

### You may need to install pywin32.
### pip install pywin32

If you really need to bring the excel window to foreground you can do this:

from win32com.client import Dispatch
from win32gui import SetForegroundWindow

xl = Dispatch("Excel.Application")
xl.Visible = True
SetForegroundWindow(xl.hwnd)

Where hwnd is the excel's window id. More information about hwnd
